WICK-RESTRICTIN G MEANS.

Application filed May 9, 1918.

and State of Ohio, have invented'a certain new and useful Improvement in Wick-Re stricting Means, of which the following is a full, clear, and exact'description, reference being had to the accompanying drawings.

' This invention pertains to the class of liquid fuel burners wherein wicks are used; and relates particularly to means for restricting the wick against withdrawal from the oil supply.

In oil stoves and lamps, particularly of the sort wherein tubular wicks are employed, it has been found that especially when the wick is comparatively long, as when new, and isturned down into contact with the bottom of the oil reservoir, the opposite sides of the lower end of the wick-for it may 'be explained. that tubular wicks are split upward some distance from their lower ends, usually at dia-metrically opposite points-become spread out and, when the wick is subf'sequently turned up, the flared sides retain "their spread out condition and lift bodily out of the oil so that instead of the oil being conducted through the wick to satisfy the name, the wick itself is burned away.

It is the fundamental purpose. of my in vention to rovide means for restricting a portion of tlie wick at all times in proximity to the bottom of the oil reservoir so that it may receive a supply of fuel as long as any remains within the reservoir; and further objects are to provide a simple and very effectual device for fulfilling the foregoing purpose and which is economical of manufacture and convenient of incorporation in oil burners of prevailing styles.

, In the accompanying drawing wherein I have illustrated an embodiment of my invention, Figure 1 is a vertical section throughv an oil burner equipped with my wick restricting means; Fig. 2 is a section on the line 2-2 of Fig. 1, lookingupward; and Fig. 3 is a perspective of the restricting means removed from the burner.

3 which has a reduced lower end that is screwed into the upper end of the reservoir and carries an outer wick tube 4 that is spaced from and concentric with the inner wick tube 2; and a fiame spreader 6 that is supported above the wick tubes and has its lower'end extending downward into the inner tube where. it has a separable connection with the usual spider 8.

A tubular wick 10 surrounds the inner wick tube 2, and at its upper end is guided -between the inner and outer wick tubes, the

same being limited in its upward movement by the flange 11 of the flame spreader; the flame spreader, in turn, being limited against undue upward movement through an interlocking engagement with the spider 8. A carrier 12 is attached to the wick for cooperation with the star wheels 13 of the wick raising spindle 14 which may be rotated within its bearing 15 by means of the operating handle or wheel`16, secured to the outer end of the spindle.

The wick is split upward from its lower end, as indicated at 18, so that the opposite sides of its lower end may spread out and lie upon the bottom of the reservoir; for it is obvious that WithoutI splitting the wick in this manner it would descend until its lower end engaged the bottom of the reservoir and practically no farther. lVicks of the character used in oil stoves and lamps are naturally more or less stiff, and their tendency to retain a given shape or condition is increased when they become oil soaked. Let it be imagined therefore that, with the wick flared outas indicated, it is elevated by the wick raising mechanism until its lower end is withdrawn from the oil supply. Nith all indications that an ample supply ofoil is in the reservoir, the flame would become smoky for want of oil and the wick would be charred and rapidly burned away. To avoid this difficulty, I employ the wick restricting means which I shall now describe. In its present form, my wick restricting means is made of a single piece of wire,I bent to form a rin 20 and from diametri cally opposed portions of which fingers 21 ,l depend. Of course any desired number of such fingers may be employed. The ring 20 occupies the extreme upper end of the reservoir 1 and surrounds the inwardly projecting neck 23 thereof, the ring being connected, as by soldering, to the reservoir at various points, connections,

y the fingers 21 extend downward and then inward reasonably -close to the wlck and at their lower ends are flared outward in prox-y imity to the bottom of the reservoir in such a way as not to interfere with the raising and lowering of the. wick but so as to effectually restrict it to a course close to the bottom of the reservoir so that at all times it will be submerged in any oil contained within the reservo1r. l

While the herein described form of my invention is very effective and wholly satisfactory, it will be understood that I do not 'limit myself to this particular modification but regard my invention as covering any means of this nature which falls within the scope of the claims annexed hereto.

Having thus described my invention, what I claim is 1.-A wick .restricting means for use with liquid fuel burners of the type wherein tubular wicks Iare supported on wick tubes and including mechanism for raising' and lowering the wicks along the tube, said restricting means consisting of spaced members opposed to the wick tube and situated in proximity to the bottom of the fuel reservoir for retaining a portion of the wick adjacent thereto.

2. A wick restricting means for use with liquid fuel burners of the type wherein tubular wicks are supported on wick tubes and including mechanism for raising and lowering the wicks along the tubes, said restricting means comprisin fingers carried by the burner structure an extending downward alongside the wick in spaced relation to the wick tube and into close proximity to the bottom of the-reservoir for retaining portions of the wick adjacent thereto.

3. A wick restricting means for use with liquid fuel burners of the type wherein tubular wicks are supported on wick tubes and including mechanism for raising and lowering the wicks along the tubes, said restricting means comprising a member surrounding the wick and'having separate portions spaced apart about 4the wick in opposed relation to the wick tube and in proximity to the bottom of the reservoir for retaining portions of the wick adjacent thereto.

4. A wick restricting means for use with liquid fuel burners of the type wherein tubu-lar wcksare employed, said means comprising a ring surrounding the wick and attached to the upper end of the reservoir and having fingers extending downward. alongside the wick and into closeproximity to the bottom of the reservoir for engagingl andretaining portions of the` wick near the bottom of the reservoir.

5. A wick restricting means forV use with liquid fuel burners of the type wherein tubular wicks are employed,`said means being formed of a single piece of wirev and comprisiingv anannular member surrounding the wick and att-ached to the upper end of the reservoir, and depending' fingers formed by loops of thewire which extenddownward alongside the wick into close proximity to the bottom of the reservoir for engaging and restricting portions of t-he wick ladjacent thereto. l.

6. A wick restricting means for liquid fuel burners ofthe type wherein tubular wicks are employed, said means comprising fingers carried by and depending from the upper end of the reservoir and extending downward along the wick and flared outward at 4 their lower ends in close proximity to the 5 bottom of the reservoir and arranged to retain portions ofthe wick adjacent thereto.

7. Wick restrictingmeans for use with aliquid fuel burner of the t pe having a wick supporting tube and-mech rocating a tubular wick. along said tube, said restricting means comprising a member carried 'by the burner structure and depending alongside the wick in spaced relation to the-wick tube and into close proximity to the bottom of the fuel container for retaining a portion 0f the wick adjacent thereto.

In testimony whereof, I hereunto affix my signature.
